AUTOMATIC HASP-LOCK.

To all whom 'it may concern.'

Be it known that LJOHN R. FRANCIS, a citizen of the United States,residing at Rochester, in the county `of Monroe and State of New York,have invented new and useful Improvements in Automatic Hasp- Locks, ofwhich the following is a specification.

This invention relates to'locks and especially to locks ofthe hinged orhasp type.

The primary object of the invention is to provide a hasp which may bebrought into engagement with a staple and automatically locked in suchengagement until released by a key, the purpose being to provide a lockof this description for attachment to freight cars and the like in orderto dispense with the usual padlock, which is liable to become lost ormisplaced.

A further object of the invention is to provide an automaticallyoperative locking bolt carried by the hasp for engagement with a stapleand means for locking said bolt in its engaged position and to providemeans whereby a key may be engaged with the bolts and turned to releasethe bolt locking means, said key also providing means for manuallymoving the bolt to release the same from its engagement with a staple.

With these and other objects in view the invention consists of thefollowing novel combination and arrangement of parts, hereinafter morefully described and illustrated in the accompanying drawings, in which-Figure 1 is a horizontal sectional view through a portion of the body ofafreight car, illustrating a fragmentary part of the door and theadjacent side wall and illustrating the improved hasp lock in plan view;

Fig. 2 is a front elevation of the subject matter of Fig. 1;

Fig. 3 is a horizontal sectional view on the line 3-3 of Fig. 2;

Fig. 4 is a vertical sectional view on the line 4-4 of Fig. l;

Fig. 5 is a cross-sectional view on the line 5-5 of Fig. 1;

Fig. 6 is a detailed perspective view of the locking bolt;

Fig. 7 is a similar view of the key.

Referring to the drawings in detail, the reference character A indicatesa portion of the body of the car and B the door, to which the improvedlock is secured.

As shown in the accompanying drawings,

are hidden or protected and when the hasp is located it is impossible toreach these screws to remove them. This hasp is provided with a casing13, `which is preferably rectangular in cross-section and has formed inits rear wall an opening 14, within which is adapted to enter a staple15 secured to the car body adjacent the door opening.

. For the purpose of automatically locking the staple 15 into engagementwith the hasp 12, the casing 13 has mounted for sliding movement thereina locking bolt 16, which bolt is positioned across the opening 14 in thepath of entrance of thestaple 15.

As illustrated in Fig. 6, the locking bolt 1,6 is formed with a reducedportion 17, intermediate its ends, which provides at one end anenlargement 18 in the form of a hollow rectangular frame 19. Theenlargement 18 is of the proper size to provide a working fit within thecasing13 and is formed within the rectangular opening provided by theframe 19 with the engaging lug 20, which is formed upon its face nextthe opening 14, with a cam surface 21, which is adapted to be broughtinto engagement with the staple 15 when the hasp is swung in the properdirection and to ride along the outer projecting portion of the saidstaple to move thebolt to one side to permit its entrance therein. l

To provide an additional uiding means for the bolt and to limit theorward movement 0f the same, the end opposite the enlarged portion 18 isprovided with oppositely extending lateral flanges 22, which are adaptedto engage the outer end wall of the casing 13 to limit the movement ofthe bolt in that direction. The boltvis urged into a position at thisend of the casing through the action of an expansible spring 23, whichhas one end secured to the enlarged portion 18 of the bolt and itsopposite end secured to the inner end wall 24 of the casing.

The position of the bolt 16 within the casing is such as to bring theengaging lock 20 across the opening 14, with the cam surface facing thesaid opening, so Vthat the staple trance through the slot.

staple and its engagement With the luO' 20 Which is again positionedacross the opening 14e through the act-ion ofthe springQB'.l F or thepurpose of holding the bolt againstl further movement and permitting therelease ot the staple, the casing 13 has secured therein a resilientlocking plate 25, Whose free end 2G is located in the path of movementof the bolt 1G and is adapted to spring into engagement With the lockingnotch 2T formed in this bolt.

The bolt 16 is further provided With a key receiving opening 28, whichopening is provided with a lateral extension 29 located in juxtapositionWith the notch 27, so that a key 30 may be inserted through the key slot31 of the casing and engage With the opening 28. A partial rotation ofthe key Within this opening will cause the bit 32 to engage they plate25 and lift it from the notch 27, when the bolt 16 may be manually movedto disengage the lug 2O from the staple 15.

In order to permit of the manual move'- ment of the bolt 16 the slot 31of the casing is elongated, so that the key is inserted in one end'ofthe slot and turned to release the locking bolt, the length of the slotpermitting of the longitudinal movement of the key to manually operatethe locking bolt. A pivoted cover 33 is secured to the casing 13 so asto exclude dust and dirt from en- The key 30 may be of various shapesand designs, the one illustrated being provided Y With a convenientoperating handle 3l, and having a shank carrying the key bit 3,2previously mentioned.

Copies of this patent may be obtaine for five cents each, by addressingthe Commissioner of Patents,

It is thought that from the foregoing description and the accompanyingdrawings, persons skilled in the art will be able to understand theconstruction, operation and various advantages of the invention. Theright is reserved to make such changes in the form and proportion.thereof as will properly fall within the scope of the appended claim.For example, the Width of the rectangular opening Within the frame 19 ofthe locking bolt may be increased and two engaging lugs provided insteadof one.

Having described the invention, what is claimed is:

A hasp lock comprising an elongate-d casing provided With an opening, aspring actuated locking bolt slidable longitudinal Within said casingand having an open top key receiving socket therein, a stationarymember, means carried by the bolt for engagement with the stationarymember, ar

spring locking plate located in said casing in the path of movement ofsaid bolt and above the open top key receiving socket, Aan engagingshoulder formed on said bolt adjacent the open top of the key receivingsocket for engagement with the spring locking plate to hold the bolt inlocked position, a key adapted for insertion in said key receivingsocket and rotatable therein to en gage the locking plate and releasethe latter from engagement With the bolt, said key beingl also movablelongitudinally oi' the casing with the bolt to slide the latter fromengagement with the stationary member.
